rgeomorphon: A Lightweight Implementation of the Geomorphon Algorithm
A lightweight implementation of the geomorphon terrain form classification algorithm of Jasiewicz and Stepinski (2013) <doi:10.1016/j.geomorph.2012.11.005> based largely on the 'GRASS GIS' 'r.geomorphon' module. This implementation employs a novel algorithm written in C++ and 'RcppParallel'.
